Having a GUI as part of the language standard would be bad for exactly
the reasons you describe. (C++ has no such thing either.) But what you
do need is first class Ada support for the GUI features of important
environments. When people are programming the iPad's multitouch screen,
they ought to be able to do that with a proper Ada API, and not have to
generate their own version by hacking one from a different language.
And it's up to Ada proponents to provide such a thing, because as things
are now, no one else will.
